RISK PREVENTIVE EXPLOSION PROTECTION CO / O 2 MONITORING AND CONTROL Ignition Source Oxygen Explosion Product DUST EXPLOSION HAZARDS exist in Mills Spray Dryers Dryers Filters Dust Collectors Silos Conveyers Separators Dedusting Screens Mixers INGNIATION SOURCES are Smouldering Nests Hot Surfaces Mechanically-Induced Sparks Sparking Electrical Equipment Flames Electrostatic Discharges PRODUCTS are combustible dust in powder-air mixtures Fire and Explosion Risks: Fires and Explosions generate high risks for people, the environment and production installations. The consequences are significant developments of heat and pressure. The fire and explosion safety of an installation is determined by risk factors of the process and products. High temperatures and material product characteristics can develop dangerous smouldering fires in the production process. A proven technology is the use of Carbon Monoxide (CO) analysis for early fire detection and Oxygen (O 2 ) analysis to control the inert atmosphere. This is recommended according to CEN/TR 15221 and VDI guideline 2263/2. Early detection of smouldering fires allows the operators to mitigate fire propagation with help of technical measures. Continuous Carbon Monoxide (CO) and Oxygen (O 2 ) monitoring is essential to ensure prevention against fires and explosions.

robecco G.A.S. robecco reliably undertakes the measurement of safety-related parameters during the operation of explosive processes. Oxygen, CO and CH 4 measurements are indispensable for operating inert gas units. The use of safety-related parameters is essential for applying preventive explosion control. Taking action requires information on the limiting concentration of Oxygen and the CO/CH 4 concentration of air-dust mixtures. Measuring and control systems have to fulfil certain requirements (ATEX Directive).
